Hi there, I have got a simillar problem; we are staying in Watford, the best way for us to get to the city is to use the rail from Watford Junction to London Euston (20min one). As far as I am concerned, this journey can be paid using contactless pay as you go but due to the fact we will need to use this connection a few times, my question is, which cap applies for the journey from Watford Junction to London Euston? Watford Junction is out of the fare zones, so which cap covers it? If I travel to Euston and then within zone 1 and 2, would the same cap cover both travels to Watford Junction and travelling within the zones?
